Specification forming part of Letters Patent No. 57,527, dated August28, 1866.

To all whom it mayconcem:

Be it known that I, J. K. LOWE, of Cleveland, in the county of Cuyahogaand State of Ohio, have. invented certain new and useful Improvements inBronzin g-Machine for Printin g 5 and I do hereby declare that thefollowing is a full and complete description of the construction andoperation of the same, reference being had to the accompanying drawings, making` a part of this specification, in which- Figure 1 is a topview. Fig. 2 is a side view. Fig. 3 is a front view. Fig. 4 is avertical section in the direction of the lines .rx in Figs. 1 and 3.

Like letters of reference refer to like parts in the several views.

My mprovement relates to a machine for v'receiving the prepared sheet,bronzin g it, and

dischargin g the same finished by one continuous automatic operation, ashereina-fter described.

A represents the frame, of a square form, and in which are arranged therollers B, G, and D, the shafts or journals of which have their bearingsin the frame.

At one side of the cleaning-roller D, and above the fur roller B or itsequivalent, is a revolving` brush or roller, E, the brushes being placedintermediately with each other, the whole surface forming a brush, asseen in Figs. 1 and 4.

F represents a bronze-box, inside of which is a feed-roller, Fl, whichis covered with canton-flannel. A handle or lever, G, pivoted at thebottom of the frame to which said box is fastened, is for the purpose ofbringing the box in contactl with the fur bronzing-rollers, as indicatedby the dotted lines a in Fi g. 4.

H is a belt passing over the roller O, then down under the roller a', upand over the roller d, then passes to the back of the frame and over theroller e, down under the roller e', and then to the front of the machineover the rollers f and f', then over the sheet-roller O, thus forming acircuit in the direction of the arrows c.

HI is a shorter belt passing round the roller O, then under the rollera' and up over the roller b, from that roller down under the roller b'to the roller O again, in the direction of the arrows c'. The shafts ofthese rollers all have their bearing's in the frame A of the machine.

The roller B is turned by means of the crank B', which is attached to apulley, I, on the side of the frame. A cord'passing from this pulleyover the smaller one, I', causes it to turn, and this, being` secured toa larger pulley, J, turns that, thus turning the roller D, the shaft ofwhich passes through the pulleys I' J.

A cord passes from the pulley J round the pulley K, which revolves thebrush E. A cord also passes from the smaller pulley K' (indicated by thedotted lines in Fig. 2) round the pulley L, which turns the roller O.

The sheet, which is size-(1 as in the ordinaryT manner of printing forbronzing, is placed so that it will pass in between the rollers O and f'and belts H H'. The crank is then turned, which turns the rollers, asbefore stated, and the sheet is passed round the roller O, down underthe roller a', and up to the roller b, where the belts H HI part and thesheet is thrown out on the table N.

The box F is brought in contact with the fur roller, as shown by thedotted lines in 4, and, as the fur roller in turnin g comes against theroller F', causes it to turn also, thus passing the bronze from the boxto the fur roller B, upon which roller it is distribnted, and as thesheet passes this roller the bronze is spread over it, and in passingthe roller D, the outside of which is covered with canton-flannel orother suitable material, for the purpose of brushing or dusting oif allbronze that is scattered over the sheet, leaving it only where it hasadhered to the sizing. The brush E then cleans the bronze off the rollerD, keeping it always clean. As the bronze is brushed ofi' it falls onthe fur roller B.

If desired, a strip (indicated by the dotted lines t' in Fig. 4) can beput iu between the rollers D and B, to keep the bronze from falling ontothe roller O as it is brushed off the roller D.

What I olaim as my improvement, and de- 3. The belts H H' and pulleys de e' f a' b sire to secure by Letters Patent, is b', in combination withthe' sheet-roller O, ar-
